摘要
目的观察柔性减影CE-boost技术用于头颈部CT血管成像(CTA)的价值。方法回顾性收集40例接受头颈部CTA检查患者,采用5分制根据整体图像质量、血管清晰度及血管树完整度对常规CTA(A组)及以CE-boost行后处理后所获图像(B组)进行主观评分,以平均CT值、图像噪声、信噪比(SNR)及对比度噪声比(CNR)对2组图像质量进行客观评价。比较2组主观及客观评价结果。结果B组针对整体图像质量、血管清晰度及血管树完整度的主观评分均高于A组(P均<0.001);B组颈部及颅内各级动脉平均CT值、SNR及CNR均高于A组(P均<0.001)。结论利用柔性减影CE-boost技术可提高头颈部CTA图像质量。
Objective To observe the value of flexible splicing contrast-enhancement boost(CE-boost)technique applicated in head and neck CT angiography(CTA).Methods Data of 40 patients who underwent head and neck CTA examination were retrospectively analyzed.Subjective evaluation of conventional CTA images(group A)and CE-boost images(group B)were performed using a 5-point scale according to overall image quality,vascular clarity and integrity of vascular tree,while objective evaluation of both groups were performed focused on the average CT value,image noise,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the main vessels.The outcomes of subjective and objective evaluations were compared between groups.Results The subjective scores of images in group B were higher than those in group A in terms of overall image quality,vessel sharpness and integrity of vascular tree(all P<0.001).The mean CT value,SNR and CNR of vessels at all levels in group B were significantly higher than those in group A(all P<0.001).Conclusion Flexible splicing CE-boost technique could improve image quality of head and neck CTA.
